ปริมาณธาตุเหล็กและกรดโฟลิคในยาบำรุงเลือดแผนโบราณ และสมุนไพรบำรุงเลือด / สุธีรา เศรษฐอภิธาน = Iron and foric acid contents in traditional haematinic drugs and haematinic herbal medicines / Suteera Setta-Apitarn
The people in Thailand have been used traditional haematinic drugs for long time. However, there were no scientific evidence to prove that these traditional haematinic drugs in markets contain sufficient essential nutrients, iron and folic acid, for red blood cell formation in human. These studies were conducted to determine iron and folic acid contents in traditional haematinic drugs and haematinic herbal medicines by atomic absorption spectrophotometry and microbiological assay using Lactobacillus casei ATCC 7469 as an assay organism, respectively. The studies were performed on 19 samples of traditional haematinic drugs and 30 samples of haematinic herbal medicines. The iron and folic acid contents in all samples studied were low. daily consumption of these drugs, it was found that daily consumption of these drugs would supply iron only 0.10-10.34 mg and folic acid 0.31-9.32 µg, which 16:30 were not sufficient for human daily requirement. Accordingly, tradition haematinic drugs are not good sources for iron and folic acid.
